Man holding a spark plug

One of the most common questions we’re asked by Providence drivers is, “When do I change spark plugs?” Whether you own a new or used vehicle, the general rule of thumb is every 30,000 miles. The distance interval can vary, however, depending on the way you drive your car. The best thing to do is to check your owner’s manual and then speak to a technician at our service center. For now, you can simply read on to learn more about how often to change spark plugs and signs they’re bad.

When to Replace Spark Plugs

Your car’s ignition can’t operate without spark plugs. What do spark plugs do? They send the voltage generated by the ignition coil to the combustion chamber, which ignites as you start the car. Because your car can’t start without good spark plugs, you’ll notice right away if something is amiss. Here are a few signs replacements are needed:

  • Misfiring engine
  • Rough-sounding engine
  • Rough noises during engine idling
  • Poor acceleration
  • Decreased fuel economy
  • Engine startup failure or slow engine start

Why Replace Your Spark Plugs?

Replacing your car’s spark plugs will help keep the engine in good shape. Additionally, you and your car will reap the following benefits:

  • Higher Fuel Economy– If your car has a worn spark plug, fuel economy can be slashed by up to 30%. Replacing the plug can help restore your car’s efficiency.
  • Dependable Combustion System – Spark plugs help keep combustion going, so your car runs reliability.
  • Easy Engine Starts – After you replace your car’s spark plugs, you should notice an immediate difference. When spark plugs are working as they should, the engine will start right up.
  • Reduced Harmful Emissions – Replacing old spark plugs can help control harmful emissions and give your car a fuel economy boost.
